Remember ^ arrow then space makes it double jump! Use the left and right arrow keys to move, up arrow to jump, space to do a spin jump and shift^ or X key to dash. And yes, I know you can double jump. ;) Thanks to @goldfish678 for finding some small Mario spin jump sprites! WORKS BEST ON INTERNET EXPLORER! Also, some of the sprites for this were from @-SuperNintendo-'s SMW level designer game. I highly recommend you check that out. It's amazing and under viewed and deserves many more loves!
Thanks Brad Games sorry for not telling right away but made a remix that you can remix add more code and make a whole level that's it scratch later!
